Results Brief Appl. Catal. B：Porous graphitized carbon-supported FeOCl as a bifunctional adsorbent-catalyst for the wet peroxide oxidation of chlorinated volatile organic compounds: Effect of mesopores and mechanistic study Wet scrubbing combined with adsorption-enhanced heterogeneous advanced oxidation processes (AOPs) is an effective method to treat chlorinated volatile organic compounds (CVOCs). A porous graphitized carbon (PGC)-loaded FeOCl catalyst was developed by the group of Mr. Jinjun Li from Wuhan University for the effective removal of gaseous dichloroethane, trichloroethylene, dichloromethane, and chlorobenzene. The PGC-loaded FeOCl catalyst was characterized by BET and analyzed for adsorption performance, and it was found that the PGC-loaded FeOCl catalyst had a well-developed mesoporous structure, which could accelerate the diffusion of organic molecules within the particles, and showed better removal performance for CVOCs.

Mr. Jinjun Li's group at Wuhan University prepared hydrophobicity-enhanced porous graphitized carbon fibers (PGCFs) by KOH-catalyzed graphitization and studied their adsorption capacity of representative VOCs, which was characterized to show that PGCFs have a high specific surface area of more than 2,200 m2/g and a micromediaturized pore structure, and that selective adsorption capacity of organics was improved under humid conditions.

Recently, Zhichao Jin's research team at Guizhou University has demonstrated that heteroatomic anions can be used as super-electron donors to initiate free-radical reactions to easily synthesize 3-substituted benzofurans. The resulting products have broad application prospects in organic synthesis and pesticide development.     The results were published in the prestigious journal Nature Communications under the title "Facile access to benzofuran derivatives through radical reactions with heteroatom-centered super-electron-donors". In the study, CIQTEK's X-band continuous-wave electron paramagnetic resonance spectrometer EPR200-Plus was used to confirm the generation of free radical species in the reaction system.   Benzofurans are among the 100 major cyclic structures widely found in human clinical drugs. In particular, 3-substituted benzofurans are frequently found as core structures in many natural and non-natural drug molecules with proven biological activity. In order to obtain 3-substituted benzofuran derivatives with a wide range of functionalities rapidly and selectively, the development of new and efficient synthetic methods is essential. Single-electron transfer reaction is one of the most efficient ways to construct functionalized 3-substituted benzofurans, and a suitable electron donor is crucial for the success of the single-electron transfer process. However, to date, no study has reported the use of heteroatom-centered anions as direct super-electron donors for single-electron transfer reactions.   The research team of Zhichao Jin at Guizhou University has easily synthesized 3-substituted benzofuran molecules with various heteroatom functionalities by utilizing heteroatom anions as SEDs to initiate the free radical reactions in their studies. Phosphines, thiols, and anilines with different substitution patterns performed well in this intermolecular free radical coupling reaction, and the 3-substituted benzofuran products with heteroatom functionalities showed moderate to excellent yields.   Fig. 1 | Bioactivities, syntheses of 3-substituted benzofurans and SEDs for radical reactions. a Commercial drugs containing 3-substituted benzofuran structures. b Typical methods for access to 3-substituted benzofurans. c Representative organic small molecular SEDs. d Heteroatom anions as SEDs for 3-heteroalkylbenzofuran synthesis.   The generation of free radical species in the reaction system was confirmed in the study using EPR technique (CIQTEK EPR200-Plus). The EPR spectra of the mixture of 1a, HPPh2 and LDA in 25°C DME showed a signal similar to the phenyl g factor at g = 2.0023.

During the 2023 World Manufacturing Congress, CIQTEK launched the self-developed "Atomic Magnetometer (SpinMag-I)", a commercial Atomic Magnetometer with low energy consumption, easy to carry, and extremely high magnetic field sensitivity, which can be used for precision measurements of cardiac, cerebral, and geomagnetic magnetic fields, with the 100,000-fold increase in sensitivity compared with the classical technology (Hall effect sensors), and is expected to breed new changes in the fields of biomedicine, industrial detection, and geophysics. Opening Ceremony of the World Manufacturing Congress 2023   Atomic Magnetometer（SpinMag-I） Atomic Magnetometer（SpinMag-Ⅰ） The Atomic Magnetometer (SpinMag-I) takes advantage of the spin nature of the outer electrons of alkali metal atoms (Rb-87) and uses a pump laser as a means of manipulation to spin-polarize the alkali metal atoms. Under the action of an external weak magnetic field, the alkali metal atoms undergo Larmor progression, changing the absorption of the detection laser, thus realizing highly sensitive magnetic field measurements. The Atomic Magnetometer is characterized by high sensitivity, small size, low energy consumption, and easy portability, which will lead mankind to enter the field of magnetic sensing in scientific research, biomedicine and other fields in the future. For very weak magnetic measurements, help cardiac and brain magnetic imaging research The detection sensitivity of SpinMag-I is less than 15 fT/√Hz. The advantage of high sensitivity leads to unique applications, the most prominent of which is currently biomagnetic imaging (brain and cardiac magnetism). Magnetic brain research equipment. Image from the web.   Brain magnetism is caused by the spontaneous or induced activity of a population of brain cells, which generates a complex biological current. This signal can be captured by SpinMag-I and reconstructed to form a mathematical image according to a certain mathematical model, thus obtaining the person's brain magnetic image. Magnetic brain imaging can be used for screening of functional diseases such as epilepsy, Parkinson's, Alzheimer's, etc., and has a lower cost compared to current magnetoencephalography based on superconducting interferometer technology (SQUID). Meanwhile, the Atomic Magnetometer also provides more technological means for cutting-edge research in brain science such as brain-like computing and brain-computer interface. SpinMag-I can also be used for cardiac magnetic measurements for functional diagnosis and research of cardiovascular diseases such as myocardial ischemia. Cardiac magnetic testing based on this method has the advantages of being non-invasive and radiation-free, and is safer than current ultrasound, CT, and nuclear magnetic methods.   Product Features Miniaturization SpinMag-I probe size is approximately 30 x 16 x 12 mm3 and continues to evolve towards miniaturization. This is due to the fact that miniaturized pro...
